Learn · Open-source growth
Your growth stack, open and yours.
Open-source, self-hostable growth means software you can read, run, and own — and customer data that lives on your infrastructure, not a vendor's. This track covers what that buys you, what it costs, and how it meets GDPR, without the myth that self-hosting alone makes you compliant.
In this guide
- 01Open-source marketing automationOpen-source marketing automation is self-hostable messaging and campaign software whose code you can read, run, and modify on your own infrastructure — projects like Mautic, Dittofeed, and Listmonk — trading the convenience of SaaS for data ownership and no vendor lock-in.Read
- 02Self-hosted customer engagementA self-hosted customer-engagement platform runs on infrastructure you control — your own servers, a VPS, or your cloud account — so customer profiles, events, and messages stay in your environment instead of a vendor's multi-tenant cloud. You trade managed convenience for control and ownership.Read
- 03Own your customer dataOwning your customer data means it lives in a database you control — exportable, auditable, and portable — instead of locked inside a vendor's platform, so a price hike, a sunset feature, or a shutdown can't strand years of customer history behind an export wall.Read
- 04Open source vs SaaS marketing toolsOpen-source marketing tools trade convenience for control: you own the data, code, and customization but absorb hosting, security, and maintenance. SaaS trades that control for managed hosting, support, and faster setup at a recurring cost. The right pick depends less on sticker price than on total cost of ownership and how much you value data sovereignty.Read
- 05GDPR and self-hostingSelf-hosting can support GDPR compliance by keeping personal data on infrastructure you control and letting you choose where it sits — but GDPR has no self-hosting requirement, and self-hosting alone is not compliance. You still need a lawful basis, consent records, data minimisation, retention limits, processor agreements, and a way to honour erasure.Read
- 06First-party data and trackingFirst-party data is information you collect directly from your own audience — through your site, app, and SDK, under your own consent — so it stays accurate, durable, and yours. It differs from third-party cookies, set by external domains for cross-site tracking, which browsers and regulators have steadily restricted.Read
